    Asteroid Impact and Deflection Assessment (AIDA) on Wikipedia

    The Asteroid Retrieval and Utilization (ARU) mission, also known as the Asteroid Initiative, is a potential future space mission proposed by NASA. Still in the early stages of planning and development, the ARU is a mission to bring a small near-Earth asteroid into lunar orbit, where it could be further analyzed both by unmanned craft and by a future manned mission. NASA hopes to complete the mission, which may take anywhere from six to ten years, in time to accomplish its stated goal of landing humans on an asteroid by 2025.

    The Asteroid Retrieval and Utilization mission, excluding any manned missions to an asteroid which it may enable, is predicted by a Keck Institute for Space Studies study to cost about $2.6 billion, of which $105 million has been proposed for 2014. NASA Administrator Charles Bolden has stated that: "This mission represents an unprecedented technological feat that will lead to new scientific discoveries and technological capabilities and help protect our home planet."

    Asteroid Redirect Mission: Boulder Collection Concept

    Published on Mar 26, 2014

    This animation illustrates one of two robotic mission concepts under consideration for NASA's Asteroid Redirect Mission. In this concept, the Asteroid Redirect Vehicle descends to the surface of a large asteroid and robotically collects a boulder from its surface.

    Asteroid Redirect Mission: Crew Segment

    Published on Mar 25, 2015

    NASA announced the next step in the plan to retrieve an asteroid boulder from a near-Earth asteroid and redirect it into a stable orbit around the moon to carry out human exploration missions, all in support of advancing the nation's journey to Mars. For NASA’s Asteroid Redirect Mission (ARM), a robotic spacecraft will capture a boulder from the surface of an asteroid for exploration by astronauts in the mid-2020s to test a number of new capabilities needed for future human expeditions to deep space, including to Mars. This animation illustrates the crewed part of ARM, showing how astronauts will travel to the asteroid using NASA’s Space Launch System (SLS) rocket and the Orion spacecraft, investigate the boulder and return a sample of the asteroid back to Earth.

    Asteroid Redirect Mission: Robotic Segment

    Published on Mar 26, 2015

    This concept animation illustrates the robotic segment of NASA's Asteroid Redirect Mission. The Asteroid Redirect Vehicle, powered by solar electric propulsion, travels to a large asteroid to robotically collect a boulder from its surface. It then conducts a "gravity tractor" planetary defense demonstration on the asteroid before bringing the captured boulder to a stable orbit around the moon where astronauts can visit, explore, and sample it.

    ESA’s Asteroid Impact Mission: the reason why

    Published on Apr 20, 2016

    ESA’s Asteroid Impact Mission, currently under study for launch in 2020 and arrival in 2022, would be humanity’s first probe to a double asteroid system. Targeting an approximately 180-m diameter asteroid – around the same size as the Great Pyramid of Giza – AIM would spend a busy six months gathering data on its surface and inner structure.

    It would then perform before-and-after measurements as the NASA-led Double Asteroid Redirection Test spacecraft impacts straight into it, in an attempt to change the asteroid’s orbital period – marking the very first time that humanity shifts a Solar System object in a measurable way. Success would make it possible to consider carrying out such an operation again if an incoming asteroid ever threatened our planet. The two missions combined are called the Asteroid Impact & Deflection Assessment, or ‘AIDA’ for short.

    But why do we need to plan such a ground-breaking experiment? Astrophysicist and Queen guitarist Brian May, ESA astronaut Luca Parmitano, the UK’s Astronomer Royal Sir Martin Rees and Canadian astronaut Chris Hadfield share their own thoughts.

    AIM: Asteroid touchdown

    Published on May 30, 2016

    As part of ESA’s proposed Asteroid Impact Mission would come the Agency’s next landing on a small body since Rosetta’s Philae lander reached 67P/Churyumov–Gerasimenko in 2014.

    In 2022 the Mascot-2 microlander would be deployed from the main AIM spacecraft to touch down on the approximately 170-m diameter ‘Didymoon’, in orbit around the larger 700-m diameter Didymos asteroid.

    The 15 kg Mobile Asteroid Surface Scout-2 (Mascot-2) is building on the heritage of DLR’s Mascot-1 already flying on Japan’s Hayabusa-2. Launched in 2014, the latter will land on asteroid Ryugu in 2018.

    Mascot-2 would be deployed from AIM at about 5 cm/s, and remain in contact with its mothership as it falls through a new inter-satellite communications system. Didymoon’s gravity levels will only be a few thousandths of Earth’s, so the landing would be relatively gentle, although multiple bounces may take place before it comes to rest.

    Light-emitting diodes (LEDs) would help AIM to pinpoint its microlander’s resting place from orbit. In case of a landing in a non-illuminated area, a spring-like ‘mobility mechanism’ would let the microlander jump to another location. Onboard GNC ‘guidance navigation and control’ sensors would gather details of the landing both for scientific reasons and to determine the microlander’s orientation for deployment of the solar array to keep it supplied with sufficient power for several weeks of surface operations.

    As well as a solar array, AIM would also deploy its low frequency radar LFR instrument, while cameras perform visible and thermal surface imaging. LFR would send radar signals right through the body, to be detected by AIM on Didymoon’s far side, to provide detailed subsurface soundings of an asteroid’s internal structure for the first time ever.

    Then Mascot-2 would repeat these measurements after Didymoon has been impacted by the NASA’s DART (Double Asteroid Redirection Test) probe, to assess the extent of structural changes induced by this impact event. AIM and DART together are known as the Asteroid Impact & Deflection Assessment mission.

    Asteroid Redirect Mission Robotic Trajectory and Crew Operations

    Published on Sep 14, 2016

    This concept animation opens with a rendering of the mission's spacecraft trajectory, rendezvous, and approach to asteroid 2008 EV5. Although the mission's target asteroid won't officially be selected until a year before the robotic spacecraft is launched, 2008 EV5 is used as a reference for mission planning details. The animation concludes with the notional crew operations that will take place after the asteroid boulder is placed in lunar orbit.

    NASA wants to save Earth with an anti-asteroid DART

    Published on Feb 15, 2019

    Who knows when a giant asteroid could crash into the planet and kill us all? But one thing's for sure: we'd better have a backup plan. Claire Reilly takes a look at NASA's mission to gently bump those killer asteroids off course and (hopefully) save humankind.
